i found a used ciener conversion kit a few years ago at the big tulsa gun show for roun 90 buks. i dont think yull find one that cheap again less your really lucky. i put it on my old argentine colt and loved it, it is the most accurate rimfire handgun, heck most accurate handgun i own now.i think a new kit runs between 2 and 300$ now if i remember right.the ciener kit is a good one, but its aluminum and painted black, may not match the finish of your gun, if that matters. oh i think they have a silver brushed alum version too.you wont regret buying one im sure, look around, ive seen several of the kits used for way less than what they were new.
